The day my father Odin banished me from Asgard, I was bitten by a vampire and had radioactive waste dumped into my eyes. To make matters worse, my mutant ability to control weather activated just as I was hit by a blast of gamma radiation. Nah, actually, I got this way by volunteering for the Weapon X program. They promised to cure my cancer. And they cured it all right, by giving me an outrageous healing factor. Then they labeled me psychotic and tossed me into a prison lab. So I escaped and became what some people might call a 'mercenary'. I prefer 'Il Capitan'.
